Hundreds of Benghazi residents rebelled Friday against the armed militias who rule the city and managed to attack the main headquarters of the extremist group, while the Libyan authorities have warned against a "chaos" . Hundreds of demonstrators managed to expel members of the Salafist group which had been accused of standing behind the attack on the U.S. consulate. The group known as Ansar al-Sharia has established the barracks in the center of Benghazi.

With chants such as "the blood of martyrs was not shed in vain," the demonstrators entered the barracks, which was ransacked, looted and burned.

Later a firefight erupted between a group which is under the authority of the Ministry of Defence and the Islamists. At least four people were killed and forty wounded in the fighting.

Libyan authorities then warned against the "chaos" and called the demonstrators "illegitimate."

President of the National Assembly, Mohamed al-Megaryef, welcomed the public reaction against the "brigades outside legitimacy." During the day, tens of thousands of Libyans in Benghazi had demonstrated peacefully against the armed militias, ten days after the attack on the U.S. consulate which had killed the ambassador of the United States Chris Stevens and three other Americans.
